The Grönefeld GTM-06 Tourbillon Minute Repeater can be said to be one of the most sophisticated Netherlands made watches. Bart and Tim Grönefeld are the proud fathers of this watch and has been made over 4 years because of the tourbillon with minute repeater complication. Because of it’s rarity, it only comes in 10 pieces packed with 18k yellow gold and 10 pieces in platinum. 385,000€.
